Differential gear ratio?
Does any one know the differential gear ratio? I am having trouble finding it.
|
Year?
|
4.44 most likely
|
it is an 04. but I am looking for the differential not the trans final drive ratio.
|
Why don't you like 4.44?
Now you've upset Staticlag. Final drive ratio (gears plus diff) is 1:1 in 5th and .84:1 in sixth...... S |
right but I am looking for the differential on the drive axle.(the limited slip differential)

Thanks that just seems awful high to me most cars are like 3.4-3.7:1

4.44......in the 04-08....4.777 in 09's trans is 1:1 in 5th(direct drive) 6th...less than 1:1 (overdrive)
|
You're sure it's not, like 3.4???
S |
no I was just looking for the exact stock number so I can go to a larger gear for more torque.
|
Mazmart on this forum sells 4.777's.....
S |
I'll never understand why people always want more gearing when it already has too much. And then they came out with the '09s and made it even worse.

yeah you're right it already has way too much torque......

since you have it all figured out.. let us know what is prudent.. beers :beer: |
I like my 4.77 gears better than all the other bolt on mods I have had (except wheels), and I have had them all.
Only thing that bothers me is the mileage and the ratio of 6th with the swap. 80mph on the interstate is pretty close to 5K rpms. :( |

Don't get me wrong I love my whip I have had it for 4 years now but just like everyone else on this site I am trying to get more power out of it and it needs help in the bottom end. And gearing has everything to do with torque. That is the purpose of a transmission the whole smaller gear driving a larger gear multiplies the torque of the engine. Even in large displacement V8's they don't produce enough torque to move the car well enough on there own. And torque is exactly what gets you moving horsepower just keeps it going and produces the top end which the car has

Silly me. I've already written about horsepower and torque elsewhere. This thread is a good place to start. It talks about the effects of horsepower and torque on engine design. However on page 2 it deals with the whole "torque moves you" thing. The second link is that post.

You have some good info in there but to put your theory to the test try putting your 8 in 5th gear(direct drivewhich is 4th gear in most cars) or a 1:1 torque multiplication from a dead stop and see where you go. It is true that hp is what will keep you going but without torque you are not getting anywhere quickly. Your horsepower is constant through you gears not your torque. And yes engines are built bigger to handle torque not hp do to longevity of the engine but when building a track car I am not concerned with engine life and driveability I am concerned with winning.

Man... Are you trying to argue with RG?.... Kind of pointless, just read his threads and learn.
